Affected Products

Product	Versions
better-auth	>= 0.3.4, < 1.6.11 (semver)
CPE cpe:2.3:a:better-auth:better_auth::::::node.js::* Remediation Upgrade: 1.6.11moderate effort Workaround:low effort Configure `session.storeSessionInDatabase` to `true`. This will cause user-deletion writes to reach the session table, allowing the database to cascade the delete. Workaround:low effort When calling `auth.api.removeUser`, also call `auth.api.revokeUserSessions({ body: { userId } })`, which uses `deleteSessions` internally. Workaround:low effort In `onLinkAccount`, explicitly call `internalAdapter.deleteSessions(anonymousUser.user.id)` before allowing the new session to be issued.
better-auth/scim	>= 1.6.0, < 1.6.11 (semver)
CPE No CPEs found in CPE dictionary for this product. Remediation Upgrade: 1.6.11moderate effort Workaround:low effort Wrap your SCIM provider's deprovisioning hook to call `auth.api.revokeUserSessions(...)` after the SCIM DELETE.
